What bottles do you use to give baby pumped milk in?

Alex • Ftm to my little prince👶🏾💙. So blessed!
My son is 3 weeks old and i am trying to avoid nipple confusion and encourage the transition between breast and bottle. I've been using tommee tippee but notice that he will play with the breast( bouncing on and off and pushing it away) before actually latching on. It takes some coaxing and soothing tk finally get him to latch on. Prior to bottle feeding he latched right away.
Thank you for any advice ;)
